7.2+ System for $4k-5k - Thoughts on a Possible Setup

[Jefferad]

Hi, I've got a friend who is looking to replace a cheap home theater setup in a small end of his basement (about 11x18). He wants to spend about $4-5k. He would rather buy fewer, quality components initially and add to it over time. I think he's interested in a 5.1.2 setup. My thoughts were:

• Buy a strong receiver that has a bit of expandability, but not too much beyond what he needs as this will already be a big step up. Dual zone support is needed as he wants to power a pair of existing speakers in another portion of the basement for music so should get 9.1 at minimum and could use some decent power as a result.
• Stick to speakers from a single, reliable vendor to make expansion and tone matching easier in the future.
• Start with a single, but quality Sub at first. Can add a 2nd later as desired.
• Use his existing cheaper speakers for height and surrounds initially. Can replace over time as desired.

Here's one option I'm thinking of recommending. Any thoughts?

• Receiver - Denon X3800H $1800 (though see note *** below)
• Subwoofer - SVS PB-2000 Pro $1200
• LR - SVS Ultra Evolution Bookshelf $1200 (600 x 2)
• C - SVS Ultra Evolution Center $800
• Total - $5k
• Later adds as desired in this order - new surrounds (pair SVS Prime satellite $400), new height speakers (pair Prime Elevation $450), a 2nd Sub ($1200)

*** I have the Pioneer VSX-LX805. I notice you can still buy this for the same as the Denon. With the discontinuation of the Pioneer line, this comes with some risk of course in terms of support, but you get more power, Dirac, Chromecast / Airplay, etc. Any thoughts on the Pioneer as an alternative?

So, what reactions do you have on this? Are there better options for the speaker vendor to go with? Thoughts on the trade-off of where the $ is going (e.g., spend less on a sub to leave more money for other elements?). Thanks!
